IMPROVEMENT IN PLOWS.

Specification forming part of Letters Patent No. IS7,950, dated February27, 1877; application filed October 3, 1876.

To all whom it may concern Be it known that I, THOMAS WIARD, of EastAvon, in the county of Livingston and State of New York, have inventedcertain Ima perspective View of a plow provided withmy improvements.Fig. 2 is a side elevation of the lower end of the wheel-standard withthe arbor secured in place. lar view with the arbor removed. Fig. 4 is asection in line a m, Fig. 2. Fig. 5 is a side View of the washer placedaround the shank of the arbor.

Like letters of reference refer to like parts in each of the figures.-

A is the plow-beam; B, the wheel; 0, the wheel-standard; D, the jointerE, the jointer-standard; F, the mold-board, and G the handles.

The standards (1 and E are each provided at their upper ends with ahand-opening, h, whereby the standards are enabled to be readilymanipulated in adjusting them on the beam, while at the same time therespective castings are rendered comparatively light and ornamental inappearance.

J represents the arbor or pivot on which the wheel B turns. it isconstructed with a flattened shank, j, the central line of which isarranged at an obtuse angle with the axis of the arbor J. K is a collararranged between the arbor J and the shank j, and having its two facesformed at right angles to the axial lines of the arbor and shank,respectively.

The collar K is connected with the shank j by a conical portion, 70, asclearly shown in Fig. 4. l is the opening formed in the lower end of thewheel-standard G for the reception of the shank j.

The opening 1' is made conical or tapering inwardly from both ends, itssmallest diameter Fig. 3 is a simi-.

being at its center, so as to form a seat for the conical portion k ofthe shank j.

On either side of the standard m is a conical washer, fitting in theopening 1, and provided with an oblong opening, a, of suitable form, tosnugly fit around the flattened shank j.

0 is a projection or lug formed on the conical side of the washer m, andp 10 two corresponding recesses, adapted to receive the lug o, andarranged in both conical sides of the opening I, so as to enable thewasher m to be readily placed in its proper position in the opening lwith reference to the shank j and arbor J, and to retain the washer inthis position against turning.

To secure the arbor J to the wheel-standard O, the washer m is firstproperly arranged in the opening 1, on the side opposite to that onwhich the arbor is required to be, and the shank j then passed throughthe openings of the standard 0 and washer m, and secured by a wedge-key,q, the conical portion, is, of the shank j bearing against one side ofthe opening L, and the washer m bearing against the opposite sidethereof, the washer being prevented from turning by the lug o fitting inone of the recesses 12 p, and the shank j being prevented from turningby the oblong form of the opening in the washer m.

The arbor J being arranged at an angle to the shank j, upon securing thelatter to the standard 0, as described, the arbor J is arranged at anangle to the plane of the standard, the inclination being forward orbackward, according to the manner of inserting the shank.

If desired, however, the arbor J and shank j may be arranged in the sameaxial line, and the two faces of the collar K be made parallel, toconform with the arbor and shank.

Having thus fully described my invention, what I claim as new, anddesire to secure by Letters Patent, is-

1. The combination, with the wheel-standard 0, provided withdouble-conical opening l, of the arbor J, having shank j and conicalcollar 1;, and conical washer m, subwasher m, provided with lug o,substanstautially as and for the purpose hereinbefore tially as and forthe purpose hereinbefore set set forth. forth.

2. The combination, with the wheel-standard (1, provided withdouble-conical opening Witnesses: l and recesses 12 p, of the arbor J.having H. A. NOTT, shank j and conical collars k, and conical ANsoN M.WEED.
